Ballistics Study of firearms, ammunition, and the impact of bullets. Determining the type of firearm used, bullet trajectory analysis, linking bullets to specific weapons.
Trace Evidence Analysis Examination of small materials (e.g., hair, fibers, paint) found at a crime scene. Connecting suspects to crime scenes, analyzing materials to determine their origin.
Forensic Pathology Medical examination of bodies to determine cause and manner of death. Autopsies, analysis of injuries, determining time of death, identifying signs of foul play.
Digital Forensic Tools Software and hardware used to recover, analyze, and preserve digital evidence. Investigating cybercrime, recovering deleted files, analyzing digital communication, tracking cyber footprints.
 

Legal Aspects of Forensic Science

Legal Aspects of Forensic Science

Forensic technological know-how performs a vital function within the prison machine, supplying medical evidence to guide criminal prosecutions and civil cases. However, the admissibility of proof and the credibility of professional testimony are crucial elements in criminal proceedings.

Admissibility of Evidence:

Relevance: Evidence ought to be relevant to the case and feature probative cost.
Reliability: The technique used to gain and analyze the evidence have to be scientifically sound and reliable.
Expert Testimony: The proof should be presented through the testimony of a certified professional witness.
Frye Standard: Some jurisdictions use the Frye Standard, which requires that the clinical method used to obtain the evidence be generally ordinary through the applicable scientific network.
Daubert Standard: Other jurisdictions use the Daubert Standard, which lets in judges to evaluate the reliability of the proof primarily based on different factors, consisting of the testability of the technique, its mistakes fee, and its peer review.

Expert Testimony:

Qualifications: Expert witnesses must have specialised know-how, skill, or education in a selected field.
Reliability: Their testimony need to be based totally on dependable concepts and techniques.
Relevance: The expert’s testimony have to be applicable to the problems in the case.
Clear Communication: Expert witnesses must be capable of give an explanation for their findings in a clear and comprehensible way to the jury.

Ethical Issues in Forensic Science:

Bias: Forensic scientists ought to be independent and avoid bias in their evaluation and testimony.
Pressure: There may be strain from law enforcement or prosecutors to obtain effects that guide a particular theory.

Forensic Laboratories and Facilities Forensic Science
